LAVATORY-BASIN, BATH, OR THE LIKE.

SPECIFICATION forming part of Letters Patent No. 615,082, dated November 29, 1898.

Application filed April 16, 1897.

To @ZZ whom, it may concern.:

Be it known that I, FREDERICK CHARLES LYNDE, a subject of the Queen of Great Britain, residing at Manchester, in the county of Lancaster, England, have invented new and useful Improvements in Lavatory-Basins, Baths, or the Like, (for which I have obtained Letters Patent in Great Britain, No. 10,629, dated May 16, 1896, and No.l2,184, dated June 4, 1896,) of which the following is a specification.

The object of my invention is to obviate the foul condition, caused by accumulation of soap and dirt, which overiow-pipes and the upper ends of waste-pipes assume after use and to facilitate the cleaning of the same.

My invention consists in dispensing with the ordinary plug and overiioW-pipe and in fitting to the outlet of the basin, bath, or the like a tube or pipe which performs the functions of waste-pipe, overiiow-pipe, and plug. I may also dispense with a permanent standpipe within the basin.

In order that Iny invention may be clearly understood, I have annexed the accompanying drawings, illustrative of the following description of the manner in which my invention may be carried into practice.

Figures I, 2, 3, 4, and 5 illustrate in section through about the center of the outlet of a lavatory-basin various forms in which my tube above named can be applied, the section of Fig. 5 being taken on a plane at about right angles to the plane of the other sections. Fig. la is a plan of the top of the tube.

- In a convenient position in the basin a I form an outlet-hole, made or fitted with a suitable outlet tube or pipe u'. Within this tube or pipe a I fit or place an inner tube or pipe b of suitable form and size, which may be provided with an india-rubber or other valve b' or washer b (see Figs. 1 and. 4) or washers. The inner tube b may be open, as seen at b3, Figs. 2 and 5, or made or provided with a detachable or other grid or openings at b4, Figs. l, 3, and 5, and a loop or handle or other means of elevating it, as seen at b5, and its 'upper end may, when the inner tube b is in its lowest position, stand either level with the outlet-hole (see Figs. l and 5) or it may project above the'outlet-hole, as seen at Figs. 2, 3

7 and 5.

tubes being due to the dierence of diameters should the tubes a b not be made a sliding fit (see Fig. 5) maybe utilized mainly for the outflow from the basin and may be covered with a grid a3, or the tube a may be utilized to increase the outflow from the basin if the opening grid or top of the inner tube b is level with or below the bottom of the basin a when at its lowest position.

I will now explain the action of the apparatus. Assuming the basin to be empty, the inner tube would be in its normal positionviz., at the lowest point within the outer tube, as seen dotted on Figs. l, 4, and 5. Owing to this position the outlet is caused to be open and the basin has emptied itself. In order to allow the basin u. to be filled, the inner tube is raised by lifting it by means of the handle, ring, or other suitable arrangement at b5, and the height of the lift may be limited by stopssay at c, Figs. 2 and 3. The inner tube l) may maintain itself in its raised position by pressure of the valve b' or washer 5X, as seen at Figs. I, 2, and 3, the said valve wedging tightly in the tapering or reduced part ax of the pipe ct', or other suitable arrangement may be adopted, such as the weighted lever d, for this purpose. (See Fig. 5.) The inner tube b, with its valve b, (or bX,) then prevents the water in the basin from passing to Waste, and the inner tube b also acts as an overiow-pipe should the water be allowed to continue to flow after reaching the level seen at A B. In order to empty the basin by allowing the water to pass to waste, the inner pipe b is pushed down and may be caused to be released immediately and fall into its normal position and be arrested by a cushion of india-rubber e, Figs. 2 and 3, or the washer of india-rubber bx, Fig. 4.

The releasing of the inner tube Z7 may be eected by means of the taper portion or collar ax, Figs. l, 2, and 3, within the outer tube a', which may both serve to retain the inner tube b when up and to release it instantly when pushed down. The passage of the water may be entirely through the tube b (see Figs. 1 and 4) or both inside and outside the inner tube b, (see Figs. 2, 3, and 5,) thereby lushing the tube b or both tubes u.' and b every time that the basin a or vessel is emptied, and for this purpose the. inner tube may IOO be held suspended in the outer tube cd, as seen at Figs. 2, 3, and 5, when in its lowest position, by means of a suitable stop c (or e', Fig. 5,) which may also prevent it from being raised too high, as seen at Figs. 2 and 3.

In order to empty the basin, the tube is pressed down and the valve is released and the water enabled to low to waste.

The inner` tube is so arranged, as seen by the drawings, that it can be readily detached from the outer tube and cleaned and the grid can be detached from the inner tube, as seen at Figs. l and 4. In order to cleanse the tube-surfaces, the action of the raising and lowering of the inner tube may be utilized for this purpose with properly-constructed washers or wipers ZJXX, as seen dotted in the raised position on Fig. l.

By moving the inner tube in a circular direction the valve U may be tightened, or the same result may be obtained by a lever or other suitable arrangements-such, for example, as are now employed for closing the neck of a jar or bottle liquid-tight.

In cases where the inner tube Y) is to be held suspended by the compression of the valve 1)'(see Figs. 2 and 3) I propose to make the valve of india-rubber, with a cavity l1" to facilitate the displacement of the rubber surface and allow the tube b and valve b to be put in or entirely pulled out, if necessary, from above.

l claim as my invention- The combination with a lavatory-basin, bath or the like having an outlet-seating, of an overIiow-tube with openings at the top and bottom and fitted to the outlet and provided with a valve at its lower end, which valve is below said outlet-seating when the outlet is open, said tube being adapted to be raised so as to raise the valve to the seating to close the outlet, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

FRED. C. LYNDE.
